Hi all,
I bought an old stone Victorian house last year, and as expected the place had a lot of mould and damp. The walls were all papered and the only heating in the house was from two storage heaters, one in the hallway one on the landing and a gas fire. No radiators or anything, and absolutely nothing in the extension that has the kitchen on the GF and bathroom on the 1st. Anyway, after having a survey done to get the mortgage the guy recommended stripping the walls up to a metre and having them injected, then re-skimmed over sand and cement !! :RpS_cursing:
I ignored him, as the walls are rubble filled and a 2 1/2' thick!. For the living room I replastered the external walls using lime, and it took forever to dry. The dining room was much worse and had cement and lime patches all the way to the ceiling. In the end I studded it out with treated timber and screwed foilback boards on and skimmed. This way looks much better than the lime method, though I appreciate it's probably not the correct way. I re-pointed outside with lime and so far so good. I'd be happy if the boards lasted 10 years, though so far there is no sign of the damp, and I'm hoping that by repointing with lime outside I've left a way for moisture to escape. Time will tell.
Anyway, I just thought I'd say after reading around the subject for ages and experimenting first hand, cement render and gyspum plaster don't suit external solid stone walls at all, DP injections can't work in rubble infill walls, lime is great but takes forever. Studding hides the issue and doesn't necessarily solve it, takes up more space but looks beaut!
